DICE has revealed that 600 per cent more people are participating in the Battlefield 3 beta than those who partook in the Battlefield: Bad Company 2 beta.

While the studio didn’t put a hard number on Battlefield 3 beta participants, the Bad Company 2 beta attracted 2 million testers in January 2010.

Six times the number of Bad Company 2 testers puts those playing the Battlefield 3 beta at around 12 million.

The news was broken by DICE general manager Karl Troedsson on the Battlefield blog: ““The biggest reason for running the Open Beta is to stress test our servers and back end. Already, we are seeing six times the number of simultaneous players in the Battlefield 3 Open Beta compared to the Beta for Battlefield: Bad Company 2. The fact that Battlefield 3 is clearly our biggest game launch ever by a magnitude of six makes it doubly important to test everything.”

“We are constantly updating the News section on Battlelog with information on what we are fixing from Open Beta to final,” he said. “We appreciate your time and your feedback. The data and feedback from the Open Beta will not only directly affect the final game of Battlefield 3, but its future development and support.”

Troedsson added that the build beta testers are playing is old and not representative of the final product.

“The Battlefield 3 Open Beta is based on software that is more than one month old. We need to test the new back end dedicated server structure we’ve built. Not only have we built a new game engine, but an entirely new back end system so that everyone can enjoy the benefits of dedicated servers on all platforms.

“Just like normal procedure when releasing a game, the Open Beta has had long lead times due to testing, certification, and setting up,” he continued. “This means that the code you are now playing is actually quite early and not representative of the final game.

“We had to do this in order to have as many people testing as possible, in order to ensure a top quality experience when the game is released. However, we’re confident in the Battlefield formula and confident that our fans will support us in order to make Battlefield 3 better.”

The Battlefield 3 beta is underway on PC, Xbox 360 and PlayStation 3. The game will be released later this month.
